Do I need to use board.connectAsync every time I use the sensor?

Weilin

If I want to use several sensors at the same time, do I need to use board.connectAsync() when using each sensor?

Or I only need to use board.connectAsync() once

If you are still connected to the sensors and the board pointer is still valid, you do not need to re-use "connectAsync()".
Please see how many examples on github.
